This invention relates to certain new-and useful improvements inpneumatic conveying apparatus of the type embodying a me-. chani'calconveyer for receiving material to be conveyed and discharging thesameinto horizontal and a vertical plane without dis- 7 turbingtheblower mechanism and the conveying duct leading therefrom, and this ingvention has as an object the provision of an improved conveyer of thecharacter described having provisions whereby the material re-I ceivinghopper may be moved to various positionsrof adjustment withoutdisturbing the conveying mechanism proper.

Another object of this-invention resides-in the provision'of an improvedpneumatic conveyer apparatus including a casing having a mechanicalconveying mechanism therein for conveying. materialsfromareceivinghopper to thepneumatic conveying duct which mechanicalconveying casing'has a sub stantially universal connection with the.

pneumatic duct to permit its movementwithout disturbing the drive ofthemechanical conveyer.-

And'a still further object of this invention resides in the-provision ofan improved pneu= matic conveyer of the character. described in whichthey mechanical conveyer casing is swingingly connected with thepneumatic conveying duct and the driveiof the mechan- Y ical conveyingmeans obtainedfrom theblower fan through a' drive connection disposedadjacent the adjustable connection of thecon veyer casing and'thepneumatic conveying duct.

With the above and ceeds, my invention resides in the novelconstruction, combination and arrangement of parts substantially ashereinafter described and more particularly" defined by the ap-f pendedclaims, it being understood that such changes in theprecise embodimentof the of Figure 1, and c Figure 182], new similar to Figure 3 Votherlobjects in view, which will appear as the description prohereindisclosed invention may be madeas come within the scopeof the claims.

In the accompanying drawings, I h i1;

Referring now more particularly to the accompanying drawings, inwhich like numerals V designate l1ke parts throughout the several views,5 designates a fan casing having ablower Gtherein, the shaft vof'which-is journaled in standards 8 mounted on a base -9 at oppositesides of the casing. 'A conveying air duct or trunk 10 has its innerendin communication with the fan easing from whi'ch'it'extends to asuitable point of'dis-I chargejnot shown, and is provided with anopeninglliin its top wall at-a point adj acent lliS connection with thefan casing with which a discharge{chamber 12' communicates, the; V

A mechanical"conveyer 15, illustrated in the presentinstance as of thescrew type, is I mounted within thecasing 1 1- and i has its shaft 16drivingly connected with the shaft 7 ofthe blower or fan so that thepower of a prime mover, notshown, connectedwiththe' shaft througha-beltpulleyfil'f likewise actuates the "mechanical conveyer.
